Abstract : A power supply has the source and drain of a MOSFET arranged for connection between an input voltage source and a load. In normal operation a bias voltage is applied to the gate to place the MOSFET in a conductive state. A difference amplifier maintains a fixed ratio between a reference voltage and the output voltage. Current limiting circuitry senses the current that the power supply provides to the load and disables the MOSFET when the current provided to the load exceeds a predetermined value. Thermal shutdown circuitry senses the operating temperature of the power supply and places the MOSFET in a nonconductive state when the operating temperature exceeds a predetermined value.
